Abstract: Recently we have presented in our group a meson exchange model for the K$^{+}$ N interaction below pion treshold which contains apart from single-meson exchange, higher-order diagrams involving $\Delta$K,NK* and $\Delta$K* intermediate states. We now extend this model above pion treshold i.) by taking into account the K*- and $\Delta$-width, calculated in a generalized Lee model; ii.) by doing a full coupled-channel calculation, under inclusion of the diagonal $\Delta$K and NK* interaction based likewise on meson exchange. It turns out that the latter interaction as well as the off-shell behavior of the widths are essential for reproducing the pion production data in both isospin channels.
